我想要的日历是健身房项目。用户可以通过日历预订健身课程。到目前为止，我已经出现了日历，但我不确定如何添加一个事件，例如“Spin class 2pm”，然后用户可以单击此预订。如果有人能指出我正确的方向，那就太好了。
我目前的日历代码：
<?php
class Calendar
{
var $events;
//create a class to store information
function Calendar($date)
{
if(empty($date)) $date = time();
define('NUM_OF_DAYS', date('t',$date));
define('CURRENT_DAY', date('j',$date));
define('CURRENT_MONTH_A', date('F',$date));
define('CURRENT_MONTH_N', date('n',$date));
define('CURRENT_YEAR', date('Y',$date));
define('START_DAY', (int) date('N', mktime(0,0,0,CURRENT_MONTH_N,1, CURRENT_YEAR)) - 1);
define('COLUMNS', 7);
define('PREV_MONTH', $this->prev_month());
define('NEXT_MONTH', $this->next_month());
$this->events = array();
}
//This constructor takes a single argument (a UNIX timestamp) and from that defines several constants that we will use in our code.
//If the argument is empty then the current date is used. An events array is also set up to hold the events for our calendar.
function prev_month()
{
return mktime(0,0,0,
(CURRENT_MONTH_N == 1 ? 12 : CURRENT_MONTH_N - 1),

}
//This function will return the timestamp for the same day in the next month (or the 1st day of the next month if the current day is not correct).
//A similar function returns the timestamp for the same day in the previous month (again will return the 1st day if the current day does not exist in the previous month).
//This is achieved by using ternary statements to return the arguments for the mktime function.

您必须回显HTML表单才能捕获事件数据，将其发送到服务器并将其保存到数据库中。
<强> HTML
<form action="newEvent.php">
<label>Event name</label><input name="eventNameInput">
<label>Event date</label><input name="eventDateInput">
<button type="submit">Save</button>
</form>
<强> newEvent.php
$newEventName = filter_input(INPUT_POST, 'eventNameInput');
$newEventName = filter_input(INPUT_POST, 'eventDateInput');
// Put this data were your events are stored (database, file, ...)
